Active clinical trials for "Myocardial Ischemia"

This study aims to discuss whether the combined treatment of traditional Chinese medicine (TCM) and western medicine for Mental Stress Induced Myocardial Ischemia (MSIMI) does effect, namely the conventional therapy for Coronary Heart Disease( CHD) combining with TCM - Xinkeshu tablets.

The purpose of this study is to evaluate the safety and feasibility of a new coronary artery stent for treating blockages in the arteries supplying blood to the heart muscle. The Amaranth FORTITUDE scaffold releases a drug (sirolimus) to reduce the likelihood of the treated blood vessel developing a new blockage. In addition, the scaffold dissolves away over time, leaving no permanent implant after the blood vessel has healed. This study will will be the first evaluation of this stent in humans.

The number and function of circulating endothelial progenitor cells (EPCs) are inversely associated with coronary risk factors and atherosclerotic diseases such as coronary artery disease (CAD) and cardiovascular high risk. This double-blind, randomized, placebo-controlled trial to evaluate the effects of cilostazol on human early EPCs and endothelial function as well as the potential mechanisms of action in patients with CAD and cardiovascular high risk.

The hypothesis is that home based clinical rehabilitation (CR) is less expensive than hospital based CR with similar clinical effectiveness. The investigators will compare the results of two forms of CR on direct and indirect healthcare costs effectiveness on mortality, morbidity, modifiable risk factors control, functional capacity measured by exercise testing, health related quality of life and satisfaction rate cost/effectiveness analysis

The superiority of a percutaneous coronary intervention (PCI) by one stent over another in terms of clinical outcome is usually documented in large randomized controlled trials (RCT). Although generated from selected study populations these data form the basis for evidence based practice (EBP) in the entire population of patients considered for coronary intervention. An inherent limitation of this approach is that study populations differ significantly from all comers in terms of patient characteristics and prognosis undermining the foundation for extrapolation of trial results to all comers. Furthermore, other trials are based on a "one-fits-all" concept, while the benefits of an "individual-tailored" approach that might be superior, is not investigated. The Purpose of the current study is to Compare clinical outcome between several CE marked drug eluting stents Compare clinical outcome between several CE marked bare metal stents Compare clinical outcome in all comers with that of the selected study population of RCT's Evolve methods to compare clinical outcomes between the generalized "one-fits-all" versus the individualized or "individual-tailored" stent selection approaches The Method employed is All comer PCI registry - single centre Randomisation of all eligible patients within the registry to one of several study stent Quality assurance in non-randomized population within the registry by periodical alternating the institutional standard stent Continuous follow up of all patients included the registry by means of systematic event detection and classification by an independent safety and end point committee Assessment of effects on quality of life by heart and health questionnaires Outcome Measures Primary endpoints: Composite of cardiac death, acute myocardial infraction and target vessel revascularisation Stent thrombosis A specifically developed Treatment Failure Rate classification Secondary outcome measures include each of the above, target lesion revascularisation and total death analyzed in a hierarchical fashion at 2, 3, 4 and 5 years. Tertiary outcome measure is self reported quality of life based on health questionnaires on general health and cardiac symptoms. Power Calculations An event rate of 20% within 5 years, a relative difference of 25% (an absolute difference of 5%), P< 5%, Power > 80% => 900 patients in each of two treatment arms. Prespecified Analysis include The MACE rates between stent types The Stent thrombosis rates between stent types The Treatment failure rates between stent types The randomized population versus non-randomized population The individualized versus the generalized Population QOL between stent types

This study evaluates the safety and effectiveness of the Momo Cobalt Chromium stent system for the treatment of single de novo lesions in a native coronary artery. The stent is coated with diamond-like carbon to decrease the risk of acute and late stent thrombosis, to increase the resistance towards corrosion and to significantly improve endothelialisation through the inhibition of elution of metallic ions.

To investigate the mid- and long-term effect of Enhanced External Counterpulsation combined with guideline-driven standard treatment on patients documented with and/or at high risk of coronary artery disease.

Sirolimus-eluting stent (SES) has been world-widely used in clinical practice in treating patients with coronary artery disease (CAD). The efficacy and safety of Excel SES (JW Medical, Shandong, China, MA) with biodegradable polymer has been proved by several clinical trials. Here the investigators design a prospective, multicenter, randomized clinical study in purpose of identifying the non-inferiority in the efficacy and safety in treating CAD patients by Firebird 2 SES (Microport, Shanghai) with durable polymer, comparing with Excel SES.

To demonstrate the safety and efficacy of the Cobra Cobalt Super Alloy Balloon-Expandable Coronary Stent System for the treatment of de novo and restenotic (previously unstented) lesions in native coronary arteries in subjects with coronary artery disease (CAD) having a reference vessel diameter (RVD) between 2.5 - 4.0 mm and a lesion length ≤ 26 mm amenable to percutaneous coronary intervention (PCI) with a single stent in subjects with symptomatic ischemic heart disease.

Restenosis requiring reintervention is still a limitation of percutaneous coronary angioplasty. Despite the use of Drug eluting stent (DES), the rate of restenosis remains 7% to 16% in diabetic patients, making it a challenging problem in interventional cardiology. Still, in clinical trials, most of these attempts did not successfully limit neointimal formation after coronary stenting. Thiazolidinediones (TZDs), like pioglitazone (pio) or rosiglitazone, are a novel class of oral antidiabetic agents currently used to treat patients with type 2 diabetes mellitus. These agents increase insulin sensitivity and, as such, have favorable effects on blood glucose levels and the lipid profile in treated patients. Beyond their metabolic action, TZDs have been shown to exhibit antiinflammatory and antiatherogenic effects in vascular cells in vitro and to limit lesion development in various animal models of arteriosclerosis. Moreover, TZDs inhibit VSMC proliferation and migration, 2 critical processes in neointimal formation after coronary stenting. Data from rodent models suggest that TZDs limit intimal proliferation after vascular injury, and in clinical studies with type 2 diabetic coronary artery disease (CAD) patients, TZDs have been shown to reduce neointimal formation as well as restenosis after coronary stent implantation. Still, it remains unclear to what extend these effects depend on the metabolic action of these drugs and what might mainly be due to the improvement in glycemic control. Recently a few reports on prevention of restenosis in type 2 diabetic patients (T2DM) with the use of TZDs as been published. All of them uses BMS as endoprosthetic devices. None of these evaluated the use of TZDs in combination with DES. Aim of the study is to evaluate the efficacy of pioglitazone in prevention of in-stent restenosis after successful implantation of a sirolimus-eluting coronary stent for treatment of de-novo "complex" coronary vessel disease in patients with T2DM and stable coronary artery disease. Study primary end-point are late-loss at 9 months.Secondary end-point include binary restenosis MACE at 1, 9 and 12 month, stent thrombosis at 12 months.
